That's 29 AC for a cost of 36,670 gp. This would leave you with a mere 12,330 gp to spend on your weapon and other goodies. Winged boots or a belt of giant's strength would be outside your price range, but you could get a +1 shock weapon for a little more than 8,300 gp.

That's 28 AC at a cost of 37,595 gp... but it gives you full move speed and lets you pick up another +1 AC from Dex later on down the line. If your DM rules that you can enhance dastana and that their enhancement bonus stacks with that of a chain shirt, it would be considerably cheaper to go dastana + chain shirt than it would be to go for any heavier armor.
